Application filed November 11,

To all whom it may" concern:

'Beit known that I, HYMAN KOPPEL, a subject of the-Czar of. Russia, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Ash-sifting Apparatus, of which the following is a This invention relates to-a'n ash sifting apparatus and its object is to provide a new. and improved device which may be directly.

connected to or combined with a range or other heater'for sifting ashes and separatin out the coarser or partly consumed. partic es of the fuel without handling the ashes or first-removing them from the range.

- In the drawings hereto annexed which I illustrate certain embodiment of the inv'enstove of the type having Figure 1"is an elevation of a range 'or 'an open base sup-ii ported ni-flegs with the ash sifting appa-' ratus shorn partly in elevation and partly in section; I

' "Fi 2 is an enlarged cross section of the ash sifting apparatus shown in Fig. 1 g

Fig. 3 is an elevation of a range or stove of the type having a closed-in or incased. base extending to the floor with a modified 1 form of ash sifting apparatus adapted to such form of range;

Fig. 4; is a plan view, partly in horizontal section of the-ash sifting apparatus shown in Fig. 3; and

' Fig. 5 is a detail illustrating a locking devicefor the split bearing hereinafter. described. Y

Referring first to the form of the invention shown in Figs. 1 and 2, which is adapts able to an. ordinary stove, A represents the stove or range having an open base supported on legs.

1 is thecasing of the ash sifting apparatus. closed on four: sides and of a rotary drum-like sieve journaledon a horizontal axis. 'The sieve is preferably in the form of a complete cylinder having solid end walls 2,2, and cylindrical openwork sidewalls 3 made of wire mesh or i.

other suitable grating or mesh material.- The end walls, 2, 2, are provided with trunnions i and 4e journaled in suitablebearings thewalls of the casing 1.

andmeshes with a relatively large gear wheel 9 which isjournaled on the inner side of thefouter end wall of the casing. The axle of gear 9 extends through the wall of the casa square socket into which the, squared end of key or crank 10 fits at the outside of the casing. The

trunnion 4 on the outer end of the sieve is similarly provided neath' the rotary stove is anj ash pan i or withdrawuor indrawer 11 which may vhe sorted through an opening in'the' and ma with a square socket to receive the key or crank so that the, sieve may its of the casing. Inclined strips 12 secured to the Walls of the casing form ledges to prevent the ashes which come down from the sieve from passing into the crevices between the sides of the drawer and the casing walls.

Apair of downwardly inclined ledges or chutes 13 are secured to the upper part of the walls of the casing and terminate in proximity to the sides of the opening in the sieve when the section 3*- is removed, and the sieve is rotated to bring the top. These ledges direct the ashes from the fire-box into the sieve but do not interfere with the com lete rotation of the sieve a stove or range the base of which is mclosed or incesed down to the door. The casing 1 of the ash sifting device is a part of the stove casing itself. The rotary cylindrical sieve 3 with its removable section 3 and sliding connections 5-6, are the same as before. The ledges '13, 13 correspond to the ledges 13, i are not hinged because the sieve cannot be iifted out through the top of the casing which is an integral part of the range.

The inner end of the sieve is supported on a trunnion at, as before, journaled on the wall of the casing. The outer end of the sieve? has a square hub which fits into a squane socket piece 14 on a short shaft 15 which is journaled in the end of bracket 16. The bracket 16 is hinged to the casing at 17 to swing forward and outward and is normally urged toward its inward or opera tive position by a spring 24:- The pinion 18 is fixed to the sh rt shaft 15, and a relatively large gear 19 journaled by a short shaft 20 on the Bracket 16 meshes with pinion 15. The short shafts 15 and 20'are each provided with square sockets into which the squared end' of a key or crank 10 maybe fitted for manually actuating the sieve. A door 21 hinged to the casing closes the end of the casing and is provided with apertures 22 and 23 registering respectively with the shafts 15 and 20. These shafts project into the apertures 22 and 23 and are readily accessible for the application of the crank or key from the outside when the door 21 is closed. When the door 21 is open and the bracket 16 is swung outwardly from the sieve, the sieve hearings will be disengaged and the sieve may be removed. bodily through the open door. i

The operation of the device in either form the opening to cient 18 in Fig. 2 save that they is substantially the same. Whenthe sieve is to be filled with ashes from the fire box,

opening to the top. The removable section V f '3 is then replaced, and with the door of the casing closed the sieve'is rotated or agitated by the key or handle 10, which may be applied either to the shaft of the large gear for rapid rotation of the cylinder or directly to the trunnion of the sieve for slower rotation or agitation. The finer ashes are -thus shaken out of the sieve and fall into the. drawer or ash pan 11, while the coarser particles remain in the sieve. 'It will be understood that this operation is performed while the door 7 or 21 is closed thus preventing the escape of dust into the room. The ash pan 11 may be. then withdrawn, emptied and replaced, and by again removing the section 3 of the sieve and rotating the sieve until the opening is brought to the bottom, the coarser or partly consumed particles may .be dumped into the pan 11.
